The following figures show the schematic description of surface irrigation methods. Surface Irrigation: In this method water flows and spreads over the surface of the land. Section 21 of 22 (21b - Choosing an Irrigation System) This Chapter Includes: Methods of applying water Effect of land slope Requirements, Considerations, Advantages/Disadvantages . Surface Method of Irrigation In this method, the irrigation method is distributed to the agricultural land through the small channels, which flood the area up to the required depth. Methods of Irrigation. However, surface irrigation has limitations because it increases the chance of human contact with the effluent. Surface irrigation is often referred to as flood irrigation, implying that the water distribution is uncontrolled and therefore, inherently inefficient. Surface irrigation (flood irrigation): It is most common form of irrigation where water is applied and distributed over the soil surface by gravity. A. Irrigation methods I. When an irrigation project has been designed for either small basins or furrows and borders, the capacity of Part 652 Irrigation Guide.

Varied quantities of water are allowed on the fields at different times. In order to achieve this, a computer model has been developed at ILRI and is named as SURDEV. Surface irrigation, with which this chapter deals, includes the general methods of flood and furrow and cor- rugation irrigation. Furrow Irrigation Basin or Level Border Irrigation Wild Flood Irrigation Graded Border Irrigation Corrugation Irrigation Surface Irrigation.

Surface irrigation is where water is applied and distributed over the soil surface by gravity. %PDF-1.3 Surface irrigation methods . %�쏢 About 90% of the irrigated areas in the world are by this method. Three major types of surface irrigation are level basin, furrow, and border strip. This goal is accomplished through consideration of the following aspects of an irrigation system, which will be discussed in this chapter: 1. IRRIGATION METHODS or Modes of Application of Water to Crops There are various ways in which the irrigation water can be applied to the fields. This has been compounded by the fact that a single method … 2.2.1 Basin irrigation 2.2.2 Border irrigation 2.2.3 Furrow irrigation 2.2.4 Uncontrolled flooding. Surface irrigation stands for a large group of irrigation methods in which water is distributed by gravity over the surface of the field (note: surface irrigation does not include spate irrigation).The three most common methods are basin irrigation, border irrigation and furrow irrigation. Hence, […] It is by far the most common form of irrigation throughout the world and has been practiced in many areas virtually unchanged for thousands of years..

Management Measure for Irrigation Water: Description The goal of this management measure is to reduce movement of pollutants from land into ground or surface water from the practice of irrigation. Surface Irrigation is a kind of irrigation where gravity works its best. Methods of Irrigation 1. Water flows over the soil by gravity for surface irrigation. A flow is introduced at one edge of the field and covers the field gradually. Surface II.
